A piece with a polished window, 340g
Remarks: Main mass
A single stone was purchased by Aziz Habibi in Morocco, 2014. The piece was sold to Jarkko Kettunen.
(C. Agee, UNM) Microprobe examination of a polished epoxy mount shows of the silicate fraction: ~85% olivine, ~5% pyroxene, ~5% plagioclase. Accessory apatite and troilite. Metal (kamacite and taenite) make up approximately 15% of this meteorite. Olivine and pyroxene grain size ranges from ~50-300 μm.
(C. Agee and N. Muttik, UNM) EMPA. Olivine Fa10.2±0.1, Fe/Mn=21±1, n=7; low-Ca pyroxene Fs10.0±0.1Wo1.7?0.1, Fe/Mn=13±0, n=9; plagioclase Ab80.4±0.8An14.9±0.4Or4.6±0.5, n=3. Oxygen Isotopes, laser fluorination (K. Ziegler, UNM), analyses on 3 acid-washed aliquots, 1.6, 1.7, 2.1 mg, gave values δ17O=0.898, 1.025, 0.759, δ18O=3.841, 3.932, 3.536, Δ17O=-1.130, -1.051, -1.108 (linearized, all permil).
Primitive Achondrite (Acapulcoite), moderately weathered.
22.5 g including microprobe mount on deposit UNM, Jarkko Kettunen holds the main mass.
